Warranty:  3 years.

Warranty applies to systems which have a battery capacity of at least 2 x daily consumption.

example, if daily use is 12kwh,  a minimum requirement of 24kwh capacity is expected.

Charge Rate for best lifespan = 0.2C  or 20A per 100Ah, so a 250Ah battery will be about 50A or less  (allowing up to 5 hours charge time)

 

Through experience, we find that ANY battery chemistry, when cycled 100% every day with high charge and discharge currents has a limited lifespan, some  LiFEPo4 batteries make it to about 3 months when worked hard
